为了提高激光器效率,一般在激光腔铜质基体上镀一层纯银或焊一层银板作腔体。后一种方法制成的腔体使用寿命长,但工艺困难。 我厂于1977年制成一台激光打孔机,激光腔体采用银板焊接结构,在生产线已使用四年,加工零件一万多件。实践证明,这种结构可靠,制作比较简 In order to improve the efficiency of the laser, a layer of pure silver or a layer of silver plate is generally used as a cavity on the copper cavity of the laser cavity. The latter method of making the cavity long life, but the process is difficult. I plant in 1977 made of a laser drilling machine, the laser chamber using silver plate welding structure, the production line has been used for four years, more than 10,000 pieces of processing parts. Practice has proved that this structure is reliable, relatively simple production
